Geological position and composition of Au-Ag ores of Central Chukotka

The Upper Yablon and Penzhina-Anadyr metallogenic zones lie within the Central sector of the Okhotsk-Chukchi volcanogenic belt. These zones are made of Cretaceous volcanic covers and bodies of comagmatic subvolcanic and extrusive varieties. Volcano-tectonic structures define positions of ore cluster...

Description
Summary:The Upper Yablon and Penzhina-Anadyr metallogenic zones lie within the Central sector of the Okhotsk-Chukchi volcanogenic belt. These zones are made of Cretaceous volcanic covers and bodies of comagmatic subvolcanic and extrusive varieties. Volcano-tectonic structures define positions of ore clusters (trends) bearing Au-Ag mineralization. Argentiferous sulfosalts and fahlerz are most typical of ore-bearing veins and veinlet zones of the Upper Yablon zone, whereas acanthite prevails among the ore minerals in the Penzhina-Anadyr zone.
